cylinder. The blotting-paper may be put on inf strips wound' spirally round the cylinder, or in any way which may be found most convenient. 'y

F is the ruler, which may be a strip of metal attached to A, as seen in the drawings, or the edge ofthe case may Abeturned up in any manner, so as to present a straight edge slightly `raised whenthe combined article is placed on the paper.

Gis the paper-cutter, which may be a continuation or extension of the edge of the case,

as seen in Fig. 3, or it may be a piece attached `to the case. When the article is placed upon the paper. this cutter, by slightly turning the case, will be brought in contact with the^paper, as seen in Fig. 3, so that the paper can bereadily torn thereby in the ordinary manner. The blotting-cylinder, being of uniform diameter throughout its entire length, will, when moved over paper, serve as a ruler for marking parallel lines with much greater rapidity and accuracy than can be done with the common flat ruler. The advantages of this combination are many, and must bev obvious to all.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The case A, spring d, and detachable end sleeves, e e, combined, as described, with the blotter-roll B, to `allow of its ready removal and replacement with new blotting-paper, as

described. i
